You should be able to apply patches in the same order/manner that you have applied them on your original SDM env.
For the multi-tenancy, that's a tricky one. I think we need to adjust our documentation to address that. Here's one way I can think -
I believe we can add: TOMCAT and an entry for WSP to the SDM_OFFLINE Procset
; -----------------------------------------------------------------------------
[ procset OFFLINE_REPORTING ]
; -----------------------------------------------------------------------------
DBADMIN
sw_ver_ctl
bpnotify_nxd
confirm_db
nx_user
; license_nxd
kt_daemon
rpc_srvr
spel_srvr
domsrvr
bpvirtdb_srvr
bopauth_nxd
bop_login
webengine
TOMCAT
;wsp_domsrvr and wsp_webengine run only on Background Server
#ifdef NX_WSP_DOMSRVR
wsp_domsrvr
#endif
#ifdef NX_WSP_WEBENGINE
wsp_webengine
#endif
So it should look like above.
Restart SDM now. You should have access to the Tomcat SDM UI. You can tweak your options per need.
Hope this helps
